摘要： A large screen display comprising an image signal source such as a computer, an original image generator, a light-transmission screen, an on-screen pointing-position detecting means, and a light-pen built in an infra-red-ray emitting modulating means, wherein infra-red rays which are modulated by pressing force generated when the light-pen is pressed against the screen by an operator are emitted and the infrared rays are detected and amplified by an infrared-ray detector and demodulated by a demodulating means and then inputted to the image signal source, so that the tone and thickness of each stroke of a figure to be drawn and displayed can be displayed.
